Case study. Plant modification.After several years of operation, one of our customers wanted to improve the performance of his hydrogen plant (steam reformer) and simultaneously convert the feedstock from naphtha to natural gas.

Our solution

As a first step, bottlenecks in the existing plant were identified by high-performance test runs and detailed process simulations. More over, the plant’s hydraulic limits were determined by the use of pressure profiles. Based on these analyses, specific suggestions for improvement were made and carried out, including the replacement of the existing safety valves and the installation of an additional low-temperature shift reactor and a pre-reformer.

Result

All work was carried out on schedule. During the test run, a capacity increase of 15 % and a successful operation with natural gas were confirmed. Since then, the plant has been running safely, reliably and with the desired higher capacity.
